Heya!!! User!!! ✌
Here's your answer friend,
==============================
==> (2√7 + 3√5)(2√7 - 3√5)
==> Therefore, by using the { (a + b)(a - b) = a² - b² } identity
we have,
==> {(2√7 + 3√5)(2√7 - 3√5)}
==> {(2√7)² - (3√5)²}
==> {28 - 45}
==> -17
================================
Is the required answer.
HOPE IT HELPS YOU :)
